How is Lead testing done?
For lead detection and subsequent quantification, blood is drawn from veins, usually from the inside of the elbow or the back of the hand, into an airtight vial and is taken to the laboratory for testing. For children, a tool called lancet can be used to take the blood samples, instead of needles. In laboratories, blood samples are treated with several chemicals and reagents and the results are interpreted, giving the amounts of lead levels present in blood.
